{"product_id":"milwaukee-18v-to-cat-18v-battery-adapter","title":"Milwaukee 18V to CAT 18V Battery Adapter","description":"\u003cp\u003eUse your Milwaukee M18 batteries on CAT 18V cordless tools, without buying into a second battery platform. Power passes straight through: Milwaukee M18 and CAT 18V share the same 18V rating. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. It removes the need to keep separate batteries for different platforms, which saves money and simplifies the workflow.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSKU\u003c\/b\u003e PTA-MIL18-CAT18\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits this battery\u003c\/b\u003e Milwaukee M18 (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBattery voltage\u003c\/b\u003e 18V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRuns these tools\u003c\/b\u003e CAT 18V (Lithium-Ion)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTool voltage\u003c\/b\u003e 18V\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHousing\u003c\/b\u003e ABS (Injected)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTerminals\u003c\/b\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCurrent rating\u003c\/b\u003e 40A continuous (80A peak at 18VDC for up to 2 seconds)720 Watt continuous at 18V nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInternal wiring\u003c\/b\u003e 5 mm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight\u003c\/b\u003e 89 g (3.1 oz \/ 0.2 lb)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDimensions (L × W × H) How It's Measured\u003c\/b\u003e 93 × 75 × 47 mm (3.66 × 2.95 × 1.85 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColour\u003c\/b\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating humidity\u003c\/b\u003e 5–95% RH\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating temperature\u003c\/b\u003e -10 °C to 50 °C (14 °F to 122 °F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eUSB port\u003c\/b\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat's in the box\u003c\/b\u003e Battery Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWarranty\u003c\/b\u003e 12 months after the date of delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRevision\u003c\/b\u003e Revision 01 (released on May 26, 2026)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose this adapter\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYour Milwaukee M18 battery and CAT 18V tools run at the same voltage, so the adapter changes the fitting rather than converting anything.\u003c\/li\u003e\n\u003cli\u003eInjection-moulded ABS, not 3D printed — no layer lines to split under load.\u003c\/li\u003e\n\u003cli\u003eSolid copper terminals, so less of the current is lost as heat.\u003c\/li\u003e\n\u003cli\u003e5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.\u003c\/li\u003e\n\u003cli\u003eCovered by a 12-month warranty from the day it arrives.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eMilwaukee M18 and CAT 18V compatibility\u003c\/h2\u003e\n\u003cp\u003eIt works in one direction only: Milwaukee batteries powering CAT tools.
